`To @ZZ whom it 7a4/cry concermj" i u Be it known that I, FRDRIG DECOPPET,A engineer, of Lausanne, Switzerland,have inl ventedcertain newand useful Improvements in AStamping Devices,

isa specification. v y y y The inventlon consists of certam new and ofwhich the following ing devices as they are' more particularly used inpost-oiiices for stamping by hand the ,let-

tersy or parcels. The said vrdevices must lbe capable of being made useo fy very quickly and at sametime of being applied very exactly upon thesurface of the letter or parcel to be stamped; Furthermore, thewell-known movable disks which vbear they letters and:

signs to befprinted and which .must be rotated once every day forchanging the date to be stamped must, on the one hand, beea'silyadjusted in their desired relativeposition and,

onlthe other hand, bey prevented from leaving this said position duringthe stamping operation, although this said' operation imparts to thewhole device very severe shocks.

The invention Icomprises a very strong but yet sufficiently yieldingconnection between stamping device, and the` invention further comprisesa veryfsimple and positively oper# ative attachment for holding themovable.

disksbearing the letters and Asigns to be printedv in their respectiveplaces and allowf In the'accompanying drawings, Figure 1 is alongitudinal section of my improved stamping device, and- Fig.4 2 is asection on the line A B of the lower portion of .Fig.i1.`jFig. 3

ing the sanne to be easily adjusted by hand is a top View of across-section onl line C D of Fig. 1. Figs. 4 and 5 are intendedft'oshow the working of the spring-pin m when the same has been deformed.accidentally in two different ways. Y

In the several figures the same letters of reference referto the sameparts. v

t is a handle of wood or other suitable material, in which is insertedasleeve the portion b of which is provided with suitable slots intendedto havethe same working asa spring-clutch onf the rod o of the operativeportion ofthe device.

The rod .c has a conical collar c', which bears the shocks of theapparatus during the stamping operation, and the saidv rod c is furtherprovided with a collar 02 and with a Spherical enlargement or head c3.

The collar kis traversed by the inner end I l V of aspiral spring "d,fixed vthereto by means of apin e, and fthe external winding ofthe saidspiral' spring d' is. firmly insertedv bev.tween a shoulder-f of thecasing fand a shoulder g ofthe cover g,l screwed to the said casing f.The enlargement orhead c3' of the y `rod- 0 engages a suitable socket/t,inserted in the caslng f. Thissaid'casing fis'traversed and serving asan axis forthe 'rotating disks 76,? which bear lon their circumferencethe engraved letters and signs 7c', which are to be stamped. The saiddisks "le are providedv in' .the well-known -manner with 'correspondingseries of,holes keach of these holes correJ l 'd spondingwith one of theletters or signs of the disk. E

Now for the purpose of adjusting the series of disks' ,7c in theirdesired relative position there is provided av U-formed pin m, havingone of its arms pointed and the'other provided with asphericalenlargement m. The pointed arm of the pin m is intended to engage the Iholes k2 of the 4disks le, and the spherical enlargement m isintendedito engage one endl of the tubular'axis a', both ends of whlchare construction of pin m, in combination with lsuitably beveled, asshown in Fig. 1. flhis" .the tubular axis and the holes k2, has for itsobject tosecure the pin in yits normal rest position, in which vitvholds the several disks 7e iny their adjusted position, whatever may bethe slight deformations to which the said pin m' maybe submitted.` Thisis'illustr'ated by means of Figs. 4 and 5, fromwhich it may be yseenthat if the-.pin m, the normal form of. which is shown in Fig. 1,happens to be wrenched either to the form shown in Fig. 4
